God has purposely chosen this means to put proud and stiff-necked man totally in debt to Him for the most important achievement in all of life. Men have accomplished much and will continue to do many great things. However, verses 19-21 expose why the wise of this world will not submit to God. The reason becomes clear in the phrase, "the foolishness of preaching" (verse 21, King James Version [KJV]). This translation is somewhat misleading in the King James; it should read "the foolishness of the message preached," as in the New King James Version (NKJV). Paul is not saying that the wise of this world reject the act of preaching but that they consider the content of the message preached to be foolish. In other words, the wise will not believe the gospel, most specifically that God in the flesh has died for the sins of the world.
It cannot be overestimated how important humility expressed by faith before God is to the overall spiritual purpose of God for each individual! Each person must know as fully as possible that Christ died for him, that his own works do not provide forgiveness, and that he has not created himself in Christ Jesus. Nobody evolves into a godly person on the strength of his own will. It is God who works in us both to will and to do (Philippians 2:13). No new creation creates itself. So, by and large, God calls the undignified, base, weak, and foolish of this world, people whom the unbelieving wise consider to be insignificant and of no account. He does this so that no human will glory in His presence. On this, a German commentator, Johann Albrecht Bengel, clarifies, "We have permission to glory, not before God, but in God."
The term "in Christ Jesus" (I Corinthians 1:30) indicates that we are in an intimate relationship with Him. Paul then details—through the terms "wisdom," "righteousness," "sanctification," and "redemption"—that God, using our believing, humble, submissive cooperation, will be responsible for all things accomplished in and through us. Some modern commentators believe that, because "wise" and "wisdom" appear so many times earlier in this chapter, the terms "righteousness," "sanctification," and "redemption" should be in parentheses because Paul intends them to define what he means by true wisdom in this context.
God, then, is pleased to save those who believe and to do a mighty work in them. This set Abel apart from, as far as we know, every other person living on earth at that time. What he did by faith pictures what everyone who receives salvation must also do to begin his walk toward the Kingdom of God. Everyone must be called of God; believe enough of His Word to know that he is a sinner who needs the blood of Jesus Christ for the forgiveness of his sins; repent, that is, undergo a change of mind toward God; and be justified, made legally righteous by having Jesus Christ's righteousness imputed to him. This enables a relationship with God to begin, and sanctification unto glorification can proceed.
